Tracking Antarctica’s Ice Shelves

Lamont’s polar scientists are back in Antarctica on missions to study the continent’s ice. Ice shelves like the Ross Ice Shelf reach out over the ocean from the massive ice sheet covering the continent, and researchers are exploring how changes in climate will affect them. Flying over the ice and using remote sensing equipment, they… read more

The Future of Deep Science

Bridgit Boulahanis, a marine geophysics graduate student at Columbia University’s Lamont-Doherty Earth Observatory, joins a team of early career scientists on their way to becoming chief scientists in a training cruise focused on seafloor exploration. They’ll be getting their first experiences working with submersibles as they dive into projects ranging from cephalopod collection to acoustic… read more

When Oceans Leak

Location: Off Southern Africa Team: Sidney Hemming and Allison Franzese Purpose: Ocean currents and climate Start Date: Jan. 30 – March 30, 2016 The Indian Ocean’s warm, salty water has been leaking into the Atlantic, spinning off giant eddies with the help of the twisting Agulhas Current. Studies suggest that in the past, this warm-water… read more

Sampling the Barren Sea

Location: South Pacific Ocean Team: Frankie Pavia and Sebastian Vivancos Purpose: ocean chemistry and biology Start Date: Dec. 17, 2015 – Jan. 28, 2016 The barrenness of life and other particulate material in the clear waters of the central South Pacific allows light to penetrate more deeply than anywhere else. Columbia graduate students Frankie Pavia… read more

Decoding the Mysteries of the Ross Ice Shelf

Antarctica’s Ross Ice Shelf covers an area the size of France and measures a few hundred meters thick above the water. It plays a critical role in stabilizing the West Antarctic Ice Sheet, and scientists are concerned about its future in a warming world. In the field, a team of scientists from Lamont-Doherty Earth Observatory,… read more

The 2015 Paris Climate Summit

The nations of the world meet in Paris starting Nov. 30 to discuss how to confront climate change. The goal: Keep global temperature from rising 2 degrees Celsius above the preindustrial average. Many scientists feel that is already impossible. But the United States, China and many other nations have committed to trying. The Earth Institute… read more
